Correspondent : GON G Cai2jun , E2mail : gcjlm @ sohu. com) Abstract : The cooling process of rolled plate only depend on feedforward model , but the existing precision of commonly used temperature models are not high enough for controlling properly the process. A differential equation was therefore deduced as the model to control the plate cooling process , of which the 1st and 2nd , especially the self2learning modifications were carried out for calculation in combination with the reform of the cooling control system for Shougangπs Plate Mill , thus providing the prec........
